Use it once.. I'm confused!!

Recently, I have been either staying up late and working overtime to catch up on plans, or rushing to Nanchang to become a special forces soldier. For a whole month, my feet haven't touched the ground, my sleep has been sparse, and my dark circles under my eyes are so heavy that I feel like I'm shaking my hands in a photo and have eight layers of shadows... I look five years older!! Last time I saw my best friend, they said as soon as they met that I was drained by life.. She handed me her life-saving eye cream with her backhand
